About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1483382477. Listed at 19 retailers as of November 4, 2026, with prices from HK$43,701 to HK$81,270, a HK$37,569 spread on the same certified stone. MOH London lists it at HK$81,270. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
